On for example optical densitometry, a first and second wave of platelet aggregation is seen, in this case for an ADP-initiated aggregation.[1]
In a platelet aggregation study, the aggregation process is started by different agonists (ADP, epinephrine etc.) and the aggregation pattern can usually conform into any of the following patterns:
| ADP | Epinephrine | Collagen | Ristocetin | |
|---|---|---|---|---|
| P2Y receptor defect[2] (including Clopidogrel) | Decreased | Normal | Normal | Normal |
| Adrenergic receptor defect[2] | Normal | Decreased | Normal | Normal |
| Collagen receptor defect[2] | Normal | Normal | Decreased or absent | Normal |
| Normal | Normal | Normal | Decreased or absent | |
|
Decreased | Decreased | Decreased | Normal or decreased |
| Storage pool deficiency[3] | Absent second wave | Partial | ||
| Aspirin or aspirin-like disorder | Absent second wave | Absent | Normal | |
